Starting tomorrow, crews will be out paving the south shoulder of Shilshole Ave NW near the Ballard Siphon Replacement Project. The project is the process of replacing the nearly 80-year-old sewer line that runs below Ballard and the Ship Canal in order to prevent sewer overflows into Salmon Bay and sewer backups in North Seattle.

Tomorrow, July 10, crews will be grinding the existing asphalt and paving to support a detour around the project site when it extends into Shilshole Ave later this summer. During the paving, Shilshole Ave near NW Dock Pl. will be reduced to alternating one-way traffic between 9 a.m. and 3 p.m. The work is expected to conclude on July 17.

King County says to expect the following during paving work:

Alternating one-way traffic on Shilshole Avenue Northwest near the project site from 9 a.m. to 3 p.m.

Traffic control signs and flaggers to ease congestion through the area

Parking restrictions in work area

High levels of activity and increased noise and truck traffic

Access to businesses on Shilshole Avenue Northwest will be maintained at all times

Typical work hours Monday through Friday, from 7 a.m. until 6 p.m.

King County says drivers should use caution and follow posted traffic signs and flaggers and to plan for extra travel time through the area. Bicyclists and pedestrians are encouraged to use Ballard Ave or Leary Way to avoid the area.
